Position Sensor Calibration

After replacement of the automatic level control sensor, the system untested code will be displayed by a continuous flashing accessory inflator switch LED with a repetition rate of 0.25 second. The self test will need to be performed and a code 12 system OK will have to be displayed on the accessory inflator switch LED before the system can function normally. Refer to Diagnostic Trouble Code (DTC) Displaying in Automatic Level Control for instructions to perform ALC self test.
